Testimonies
Nissan of McKinney (McKinney, TX)

As a service manager and a technician I have been in the car business over 20 years. I have had the opportunity to work with several chemical companies, and would have to say ZAK is far and away the best. In the last 4 years I have worked with their products at 2 different stores. In each store we have been able to double or more our customer pay sales. The service advisor training and support from local reps is second to none. We are provided with all the tools we need to sell the products effectively including menu boards, hand held menus, signage and equipment. I would recommend them to any service manager who wants to look like a hero by increasing customer pays sales!
